Study Notes

Personal Protective Equipment (PPE) in dental laboratories includes: disposable gloves, utility gloves, masks, and lab coats/jackets.
Disposable gloves should be used for direct contact with contaminated items, changed and disposed of appropriately after procedures, and hands washed before and after use.
Utility gloves are for cleaning/disinfecting equipment and surfaces.
Masks, protective eyewear, and lab coats/jackets must be worn during fabrication processes, changed daily, and not worn outside of the lab.
Unit-dose concept is used to minimize cross-contamination by dispensing enough material for a specific procedure before patient contact and disposing of excess.
Chemical disinfectants must be effective at killing microbes and not damage impression materials or resulting gypsum casts.
All employees must be properly trained to handle disinfectants and they must have EPA registration numbers and intermediate-level of activity for tuberculocidal disinfection.
Incoming items are rinsed, disinfected, and annotated with the disinfectant and time used, while outgoing items are cleaned and disinfected before delivery to patients.
Impression materials can be affected by composition, concentration, exposure time, and compatibility with specific disinfectants, and manufacturers should be consulted regarding compatibility.
Disinfecting impressions can be done by spraying, dipping, or immersing, but immersion disinfectants should only be used once before discarding, except for glutaraldehydes.
Dimensional stability is not significantly affected by immersion technique, but some materials show distortion, and some adverse effects have been reported on certain materials when immersed in specific disinfectants.
Different materials require different disinfection methods: alginate, zinc oxide eugenol, impression compound, and elastomeric materials like polysulphide and addition silicone.
Exposure time to disinfectants should be based on the manufacturer's recommendation for tuberculocidal disinfection, and iodophors, sodium hypochlorite, chlorine dioxide, and phenols are common disinfectants.
Polyether materials cannot be immersed in disinfectants due to potential absorption and distortion.
Disinfection is important to prevent the spread of infection and ensure proper fitting and function of prostheses.
